J. Application December 14, 1950, Serial No. 200,885 15 Claims. (Cl. 153-54) The present invention concerns the reconditioning of containers such as barrels, drums and the like constructed of metal.

It is an object of the invention to provide a device end chime resealer which rounds out badly dented chimes, reseals and salvages substantially all chime leakers, assuring both maximum recovery in salvage and maximum service of the reconditioned drum.

It is an object of the invention resealer for drums to be reconditioned WhlCh is fully It is an object of the invention to provide a chime resealer which has an adjustable production speed which can be coordinated to a desired line output. The invention can be operated at five drums per minute with ease.

It is an object of the invention to reseal both ends of a drum simultaneously or only the one end of an open head drum as required.

It is an object of the invention to provide a chime resealer which is both automatic and easily adjusted for double-ended and open head drums.

Other objects will appear as the description proceeds. In the drawings like members refer to like parts throughout.

A frame 10 is mounted as a unit on a skid 11 and supports an anvil roll mer roll assembly on frame 10 rails 15 with drum to be salvaged between hammer rolls 13 in such ammer rolls 13 are journaled in thrust bearings 17 and needle bearings 18 supported by frame 10 and driven by a two horsepower syncrogear fifty-six R. P. M. motor 19 through sprockets 20, 21 and chain 22. Hammer roll assembly 13, including motor 19 and 26 is duplicated, one on each side of the machine. assemblies are mounted on trolley wheels erating position through the operation of equalizing linkage arrangement 27.

Linkage 27 comprises three links The end links are and the middle link is pivoted assured because movement of the links about the mid-point of the middle link is duplicated on each side.

Anvil rolls 12 are mounted on vertical axis on carriage 12 rotate in bearings 31.

The hammer rolls 13 are shown in plan in Fig. 3 with bearings 17 and 18 enclosed within a hood memerI 32 supported in channel mountings rol s 13 of one eighth on the drum ried by arms 37 which are pivoted to carriage 26. The

114 and 115 controlling through four pipes 116, 1.17, 118 and 119, likewise respectively.

Pipes 116, 117, 118 and 121, 122, 123 and 124 as indicated by gauge 128, 129, and 131, respectively.

For preferred operation and control valve 112 is adgauge 128 indicates and valve 115 is adjusted so that gauge 121 reads sixty pounds for carriages 26 closed. Once the regulator valves are adjusted they may be locked by regulator lock nuts 132.

The operation of the chime resealer is as follows:

Air is supplied to supply pipe 125 at about seventy-five pounds per square inch. Motor 101 operates cam shaft 107 and valves 112 through 115 through a complete cycle in twelve seconds. Adjustment can be made for a longer period by step cone pulleys 105.

Referring to Fig. 4, line 116 supplies air to the right side of cylinder or servo 24 to open or move carriage 26 apart to receive a drum. For this operation valve 121 is adjusted so that gauge 128 reads forty pounds as explained above. A single regulator valve andgauge could be used when the required pressures are the same.

As cam shaft 107 rotates, cam 108 opens valve 107 admitting air at about forty pounds pressure to the right hand side of cylinder 24 by means of pipe 116. This pressure moves rod 25 to the left pushing carriage 26 on trolleys 23 and left hammer and anvil rollers with it. Linkage 27 causes the right carriage 26 with the right hammer and anvil rollers to move to the right. Anvil rollers 12 are down. Cam 109 then opens valve 113 admitting air at seventy pounds pressure to cylinder 43 through pipe 117. Piston rod 42 moves kick out pusher bar 41 up to remove any finished drum between hammer rollers 13 and through link 44 lowers stop arm 48 to release the next drum which rolls down rails 15 into position on cradle 14 between hammer rolls 13. Spring 49 lowers bar 41 and rotates arm 47 clock-wise on the release of cylinder 43 by cam 109. This action raises stop arm 48 and permits drums on guide rails 15 to roll forward.

Cam 110 operates valve 114 and admits air at sixty pounds pressure to servos 28 which raise anvil rollers 12 so that the chimes at the head and bottom of a drum rest thereon or very nearly do so. Cam 111 operates valve 115 and admits air to cylinder 24 through pipe 119. This action moves carriage 26 toward the drum and causes the rotating hammer Wheels 13 to round and reseal the chimes in cooperation with hammer rollers 12. As soon as the chimes are rescaled cam 109 opens valve 113 and the cycle is repeated.

While there has been described what is at present considered to be the preferred embodiment of this inven tion, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention, and it is, therefore, intended in the appended claims to cover in generic terms all such changes and modifications as fall within the true spirit and scope of the invention.
